My solar panels stopped working recently and its a good opportunity to upgrade from 20 watts for more power.
I have been searching for good quality at good prices and came across an ebay site called Sun Solar. They have very low prices and free shipping!
$1.95/watt New 30 watt Sun Solar Panel PV Mono-crystalline 25 Years Warranty | eBay
30 watt for Mono Crystal for $55.50
40 Watt Mono Crystal panel for $75.60
The aluminum frame is anodized and they have a 25 year performance guarantee and a 2 year material warranty. They say they have been in business since 1998 and they have good Ebay Feedback.
These prices are easily a third less then companies like SunWize.
They justify their low prices by being direct sellers of their own products that are manufactured in their Chinese factory, but I am concerned that it may be poor quality and too good to be true!
If anyone has any experience or concerns with Sun Solar, please let me know.
